This invention relates to radiators and more particularly to that character of radiator known as the vertical water tube type.

The invention has among its objects to improve generally devices of this character by Asimplifying and consequently cheapening the cost of manufacture and at the same time maintaining a high degree of efficiency. The several objects of the invention as well as various advantages and novel details of construction will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein;

Figure l is a front elevational view ,of a radiator constructed in accordance with this invention;

Figure 2 is a` detail end elevational View of two of the tube sheets removed, and

Vpartly in section and partly in elevation taken substantially on the plane indicated by line 3-3 of Figure 1.

Referring now particularly to Figures 1 to 3 of the drawing, it will be noted that there is illustrated a radiator including upper and lower headers 10 and 11 adapted to be connected by a plurality of water tubes 12 herein shown as comprising flat hollow members shaped to simulate a plurality of vertical tubes.

Each flat tubular member or radiator section 12 consists essentially of two sides or sheets 13 arranged in spaced parallelrelation and as the construction is shown, each section may be formed by employing two sepa.- rate sheets united at their vertical edges as indicated at 14. Each member may however be formed from a single sheet of material bent longitudinally thereof and having its freeV longitudinal edges united as is well known in this art.

Each sheet 13 is shaped to provide a plurality of vertically extending spaced ribs 15, the ribs on the opposed sheets 13 coinciding so that when the sheets 13 are assembled these ribs will be arranged in abutting relation, thus spacing the sheets apart as clearly illustrated in Figure 2 and defining or simu-A` lating a plurality of vertically extending Serial No. 98,395.

water tubes or passages 16. The upper and lower ends of the sections 12 are connected to the headers 10 and 11 in any welllmown manner such for instance as suggested in Figure 3 by extending the `adjacent end of the section through a suitably shaped aperture in the wall of the header and soldering the I same along the joint such as indica-ted at 1l Each of the tube sheets or sections`12 is' formed with a plurality of outwardly eX- tending rib like protuberances 18 which eX- tend transversely of theV sheets 13. These outwardly extending protuberances interrupt the vertically extending ribs 15 lat the points at which they intercept these ribs. While any desired contour may be effected in these ribs they are herein shown ascurved laterally out of their general direction it being preferable however that all of the ribs be similarly shaped and uniformly spaced so thaty when assembling the radiator` the corresponding ribs on adjacent radiator sections 12l may be caused to abut to thus space the radiator sections and to providey air passages A between position of the vparts may be united as for instance by soldering the same together at the abutting portions of the ribs or protuberances 18. Furthermore, inasmuch as these protuberances ext-end outwardly from the sheet and the recesses formed thereby communicate with the interior of the sections 12 the water contained therein lis subjected to the directconnection with the radiator frame and the upper and lower headers the opposed protuberances of adjacent sections are brought into abutting contact and serve not only to properly space and align the radiator sections, but also to form tortuous air directing passages between the sections. By stamping these protuberances outwardly from the walls of the sections laterally directed water chambers are produced which extend into the path of the air to increase the heat dissip'ating eficiency of the apparatus. As suggested in Figures 1 to 3 each section may be additionally provided with inwardly directed ribs or protuberances providing spacing means for the .walls of each section to insure against the collapsing of the sections. Also in such a construction these vertically disposed ribs or protuberances define vertical water passages for directing and distributing the water throughout the thickness of the radiator to further insure eilicient heat dissipation.

vWhile the invention has been described somewhat in detail in' connection with several moditicationsof the same it will be read` ily apparent that the invention is capable of expression invarious other forms and to this end reservation is made to make such changes in. detailsof construction as may come withinl the purview ofthe accompanying claims.

lVhat I claim as my invention is: l. A radiatorformed of sections, each comprising a pair of plates arranged parallel to each other and connected together at their .vertical edges to form a water passage therebetween, inwardly extending protuberances formed in said4 plates, opposed protuberances abutting and outwardly directed, longitudinally curved protuberances formed in said plates for spacing adjacent sections and deningtortuous a-ir passagesbetween said sections.

2. A radiator formed of sections, each comprising a pair of plates arranged parallel to each other and connected together at their vertical edges to form a water passage therebetween, inwardly extending protuberances formed in said' plates and outwardly extending longitudinally curved protuberances formed in saidA plates, the opposed inwardly extending. protuberances of adjacent plates abutting and the opposed outwardly extending. protuberances of adjacent sections abutting. j

A radiator formed of sections, eac-h comprising a pair of plates arranged parallel to each other and connected together at their vertical edges toform a water passage therebetween, inwardly extending protuberances formed in said-plates and outwardly exte'nding protuberances formed in said plates and shaped to form tortuous air passages between said sections. Y

4. A-radiator formed ofsections, each comf lprisa-11g subst.a1-1tallyl flat Compartment C011- stituting a water chamber with the opposed walls thereof shaped to form a plurality of spaced inwardly extending protuberances extending from the top to the bottom of the radiator' and abutting to space said walls, and with a plurality of outwardly extending protuberances arranged to abut the corresponding protuberances of the next adjacent section and to form continuousair passages between said sections.

5. A radiator formed of sections, each comp rising a substantially flat compartment constituting a water chamber with the opposed walls thereof shaped to form a plurality of spaced inwardly extending protuberances abutting to space said walls and to divide said water chamber into vertical water passages and provided further with a plurality'of outwardly extending protuberances arranged to abut the corresponding protuberances of the next adjacent section, the said outwardly extending protuberances forming horizontally arranged air and water passages between said sections.

6. A radiator formed of sections, each comprising a pair of plates arranged parallel to each other and connected together at their vertical edges to form a water passage therebetween, inwardly extending abutting protuberances in said plates dividing said water passage into a plurality of spaced passages and outwardly extending protuberances in said plates forming tortuous air andy water passages between said sections and at an angle to said first mentioned'water passages.

7. A radiator formed of sections, each comprising a pair of plates arranged parallel to each other and connected together attheir vertical edges to form a water passage therebetween, inwardly extending protuberances in said plates dividing said water passage into a plurality of spaced passages and outwardly extending protuberances formed in said plates, spaced to abut the corresponding protuberances on the adjacent section and longitudinally curved to form tortuous water passages angularly arranged with respectt0 said first mentioned water passages and tortuous air passages between said sections.

In testimony whereof' I aflix my signature.
